What is the process When proteins help molecules move across the membrane is called?
when proteins help molecules move across the membrane, it it called Facilitated Diffusion
Which process requires energy to bring molecules across the cell membrane?
active transport
What kinds of molecules freely diffuse across a semipermeable membrane?
Water molecules freely diffuse across a semipermeable membrane.
What is the process in which molecules move across the cell membrane from a region of low concentration to a region of high concentration?
Active Transport - the process of moving particles across a cell membrane against a concentration gradient <- right one
What process drives molecules across a membrane against a concentration gradient?
Active Transport.

What process do water molecules cross the cell membrane?
Process in which water molecules moves across a membrane?
How do larger molecules move across epithelial membranes in the capillaries?
Large molecules are transported across a cell membrane by the process of process of exocytosis. This is when secretory vesicles secretes large molecules by the fusion of vesicles with the plasma membrane.
Is diffusion of molecules across the cell membrane the most complex type of active?
No, diffusion of molecules across a cell membrane is a passive process, not active, and arguably the least complex.
Which process requires energy to bring molecules across the cell membrane?
active transport
Process when large molecules food and other substances are packaged and moved across the membrane?
bulk transport
What kinds of molecules freely diffuse across a semipermeable membrane?
Water molecules freely diffuse across a semipermeable membrane.

What process drives molecules across a membrane against a concentration gradient?
Active Transport.
What helps molecules diffuse across membrane through transport proteins?
A process known as passive transport helps molecules to diffuse across a membrane. Passive transport does not involve the use of chemical energy, unlike active transport does.
Active transport is the process of what?
Active transport is the process of molecules being moved across a membrane using energy. Passive transport moves the molecules without using energy.
